LOCOMOTIVE JOURNAL LUBRICATOR.

Application filed July 19,

To aZZ "whom. it may cmzccm:

Be it known that 1, lines J. Hnnnnssr, a citizen ofthe United States, residing at New York city, New Yoi'l ,-l1ave invented a certain new and useful Improvement in Loco motive Journal Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. forming part of this specification.

My invention relates generally to lubricating devices and more particularly to a locomotive journal lubricator of the general type disclosed in my copending application; Serial Number 250,0at5,v filed Augict 15. 1918; Serial Number 352,098, filed January 17, 1920, and Serial Number 397,342, filed July 19, 1920.

The principal objects of my present invention are, to generally improve uponand simplify the construction of the lubricating devices disclosed in the applications aforesaid; to provide a relatively simple lubricating device that is entirely automatic in operation; to provide a lubricating device which. by virtue of its relatively simple construction, may be easily and cheaply produced; to construct a lubricating device so that its parts may be readily assembled or taken apart thereby greatly simplifying and facilitating inspection, adjustment. and repairs; and, further. to provide a device. that is positive in action and effective to a high degreein performing its intended functions.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompany ing drawings. in which Figure 1 is a vertical section taken lengthwise through the center of a locomotive journal lubricator of my improved construction.

Figure 7 is a detail section of the selfadjusting push rod that is utilized for actuating the plunger of the liquid lubricant pump. Referring by numerals to the accompanying drawings, which illustrate a practical embodimentof my invention. 10 designates the main body of the lubricating device, the same being preferably formed of cast or pressed metal and in the form of an opentopped receptacle. the side walls of which extend a substantial distance above the end walls and the upper edges of the latter being curved in order to conform to the radius of the journal to which the lubricator is applied. This construction of the body or container .10 permits the same to partially enclose the lower portion of a locomotive journal or the like and said body or housing can be s cured in any suitable manner to parts of the locomotive frame that are ad j acent to the journal.

Depending from the outer portion of the body or container 10 is a casing 11, the chamber 12 within which serves as a well for containing the supply of liquid lubricant that is circulated through the device. Centrally arranged within the lower portionof body or container 10 is a longitudinally disposed rod 13, the end portions of which are detachably arranged upon the end walls of the container, and formed integral with or fixed to this rod is a vertically disposed tubular member 1&1. that extends downward into the liquid lubricant well 12. The lower end of this tubular member 14 and its upper end are open and formed through the wall thereof near its lower end are ports 15 which admit liquid lubricant from the well into the chamber within said tubular member.

Arranged for reciprocatory movement within the tubular member 14 is a tubular plunger 16 provided adjacent to its lower end with an internally arranged valve seat 17 upon which is adapted torest a valve 18. This valve is held upon its seat by a compression spring 19. the upper end of the latter bearing against the underside of a perforated screw plug 20, that is seated in the upper end of plunger 16. Formed in the outer surface of plunger 16 are oppositely disposed notches 21 and loosely arranged therein are the forked ends 22 of a horizontally disposed arm of a bell crank 23.

Suitable openings 24 are formed in the tubular member 14: for the accommodation of the plunger engaging arms 22. Bell crank 23 is fulcrumed upon a pin 25 that is seated in suitable webs or brackets 26 that are formed integral with red 13 and tubular member 14, and the upper portion of the vertical arm of this bell" crank is bifurcated to form a pair of arms 23 that-engage in suitable notches that are formed in a plunger operating rod 27. This rod is arranged for reciprocatory movement in an axially disposed bore 28 that is formed in that portion of the rod 13 between tubular member 14. and the inner end of the body of the container 10, and positioned on the outer end 01 said rod 27 or that end which projects beyond the inner end wall of container 10 is a head or disk 29 that is adapted to be engaged by the face of the adj aeent wheel hub.

The inward movement 01" rod 27 is yieldingly resisted by a compression spring 30 that is arranged upon the inner end of said rod and bears against a shoulder thereupon and against an oppositely disposed shoulder formed within rod 13. Positioned within the container 10 and above the rod 13 and parts associated therewith is an open-topped waste pan or container 37, the central portion of the bottom of which is bent upward throughout its length to form a longitudi' nally disposed inverted U-shaped portion 38 that lies immediately over and partially encloses the rod 13, Formed in this inverted U-shaped portion is a suitably located aperture 39 that accommodates the upper end of tubular member 14:.

Removably secured to the end walls of the pan or container 37 are relatively thin blocks 40 of" weodoranalogous material, the upper edges thereof being curved to conform to the radius of the journal to which the lubrieating device is applied, and these wooden blocks perform the functions of combined dust guards and packingmembers to restrict the outward low of liquid lubricant from the ends of the waste pan or container. The

' pan or container 37 is yieldingly held against the underside of the journal with which the lubricator is associated by means of a spring ii, the central portion of which is bent into inverted U-shape so as to extend upwardly over the rod 13 and the end portions of said spring being extended laterally and bent upwardly to form resilient arms which engage beneath the side portlons of the pan I 0r receptacle. (S Fi 2 In Figure 7 I have illustrated an arrangement whereby the plunger actuatingpush rod is rendered self-adjustingso tnat it will yieldunder abnormal lengthwise movement and thus prevent the breakage of some part of the. pumping mechanism. This particular construction is described in deta l tainer 37 to make direct contact with the un-;

derside of the journal. and a suitable supply of liquid lubricant 1S placed in wel 12 Ol container 10.

The axle having the journal to which the device is applied always has a certain amount of lateral movement during operation, and as the wheel carried by said axle moves toward the lubricating device, the face of the wheel hub-will bear against head or disk 29, thereby moving the same and the push rod 27 a slight distance lengthwise through red 13. Asa result of this movement of the push red, bell crank 23 will be actuated to move pump plunger 16 downwardly in tubular member 71 i and as the lower end of said plunger passes ports 15, a portion of the liquid lubricanttrapped in the hiwer portion of the chamber in member il l; will be forced upwardly past check valve 1? and a correspondinamount of liquid lubricant will be. forced from the open up per end of tubular member 14:, it being un derstood that the chamber within the plunger 16 and the chamber in the upper portion oi the tubular member 14 are filled withliquid lubricant after the device has been in operation for a short time, c U

The liquid lubricant thus forced from the upper end'oif-tubular member 14 will pass directly into'the body of waste within the pan or container 37, and thus the body'o'l waste is maintained 1119i saturated eondition and the liquid lubricant willibe applied 1 directly to the underside of the. ournal with I [is the wheel hub recedes or moves away.

which. the waste is in constant contact.

from head or disk 29, compression spring 30 will act to return the parts of the pumping mechanism to their norinal positions and the operations just described will be repeated as the "wheel hub again moves toward the lubricatin device. As a result of these continued operations, small quantities of oil are intermittently delivered into the body of waste within the pan or container 27 thereby keeping; the-latter satu "at ed and affording continuous lubricationfor the journal with which the device is.

and removed from the container 10 for tie purposes of inspection, adjustment or repairs. carried thereby can be easily and quickly removed from the container 10.

Sl lubricating device 01. my improved construction is comparatively simple. may be easily and cheaply manufactured, can be advantageously employed in connection withpractically all existing types of. locomotive journal boxes, is whollyautomatic in operation, and is very etiective in pumping liquid lubricant to the waste or like fibrous material that makes direct contact with the journal of the axle. thereby insuring constant lubrication for that portion of the journal that engages the brass or journal bearing.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved lubrieating device can be made and substituted for those herein shown and described. without departing from the spirit of my inven tion, the scope of which is set forth in the appended claims.
